Support for gradient directly in theme configurations in material-ui

Right now we can configure the theme in material-ui as follows.

import { createMuiTheme } from '@material-ui/core/styles';

const theme = createMuiTheme({
  palette: {
    primary: {
      main: '#ff4400'
    },
    secondary: {
      light: '#0066ff',
      main: '#0044ff',
      contrastText: '#ffcc00',
    },
    // error: will use the default color
  },
});

Is there a way to provide gradient configuration for primary and secondary colours? IMHO subtle gradients give better colour pops and make the flat colours slightly less boring

You could set gradient values inside of your theme:

const theme = createMuiTheme({
  palette: {
    primary: {
      main: '#ff4400',
      mainGradient: "linear-gradient(to right, tomato, cyan)",
    },
    // ...
  },
});

And then use this value inside of components style prop:

<AppBar
  position="static"
  style={{ background: theme.palette.primary.mainGradient }}
> ...

EDIT

This is indeed feels hacky, but i believe this is the only way at the moment. I haven't found any examples of this in the MUI docs. And if you check out the source of <AppBar /> component, you'll find out that it is impossible to use main, light or dark colors as linear-gradients:

export const styles = theme => {
  //...

  return {
    /* ... */

    /* Styles applied to the root element if `color="primary"`. */
    colorPrimary: {
      backgroundColor: theme.palette.primary.main, 
      color: theme.palette.primary.contrastText,
    },
    /* Styles applied to the root element if `color="secondary"`. */
    colorSecondary: {
      backgroundColor: theme.palette.secondary.main,
      color: theme.palette.secondary.contrastText,
    },
  };
};

As you can see backgroundColor is used here. It would be invalid to set linear-gradient(...) to it.
